Application filed. October 25, 1919. SerialNo. 333,337.

*To all whom it may concern: v

Be it known that I, Own FRANKMAN,

estate owner, a citizen of the Kingdom of Sweden, and residing at Malmo,Sweden, have invented a new and useful Device for Periodic Emptying ofReceptacles, of which the following is a full, clear, and exactdescription.

This invention relates to a device for periodic emptying of receptaclescontaining goods in the form of a mass or in pieces, in order ifthe'receptacle is transportable to deliver the goods in heaps atpredetermined places and to prevent its distributing along the wholepath passed by the receptacle, which would be the case if the emptyingwere going on continuously. Such a requirement is at hand in connectionwith beet-harvesters and the like and the invention has for its objecttogather-the beets or tops picked up during the working of the machinein receptacles, which are emptied at predetermined intervals so that thebeets or tops are delivered in heaps on the ground whereafter theirremoval from the field is essentially facilitated.

The invention is illustrated in the accompanying drawing, in whichFigure 1 shows a longitudinal section of the receptacle. Fig. 2 shows aplan View of the same.

The receptacle consists of three fixed side walls 1, 2 and 3, and themain feature of,

the invention is to be seen therein that the fourth side 4 (Fig. 2)consists'of a plate or grate turnable around an axle5 at the upper edgeand that the bottom of saidreceptacle consists of a belt conveyer 6running over two rollers 7and 8, of which the former is arranged beneaththe movable side wall at and the other beneath the opposite fixed sidewallr2. One of the roller shafts, for instance the shaft 9 carrying theroller 8, is set into rotation by a suitable driving gear atpredetermined intervals and it rotates every time during so long aperiod that the part of the belt resting upon the roller 8 passes to theroller 7 and vice versa, 2'. 6. half a revolution. The shaft 9 isconnected with an intermediate shaft 11 by means of a bevel gear 10 saidshaft 11 carrying a sprocket wheel 12, which is connected with asprocket wheel 14 by means closed position.

of a chain 13. The wheel 14 is mounted upon the shaft 5. This shaft, asshown in the drawing, is provided with two (or more) plates or grates 4,and the gear 1014 is constructed in such a manner that the shaft 5 turnshalf a revolution during I i the movement of'the belt referred to above,and the uppermost plate or wall 4: takes the place of the lower'one whenthe emptying is carried out. The shaft 5 must rotate in the directionshown by the arrow in Fig. 1, z'. e. the movable wall of the receptaclemust open toward the side of delivery. As to facilitate the emptying andto prevent the belt from being pressed down between the rollers becauseof the weight of the goods the upper portion of the belt may besupported by fixed supporting bars or rollers in a suitable manner sothat slacking of the upper portion of the belt part is prevented.

Having now described my invention 'I declare that what I claim is:

A device of the character desoribedco mtraveling toward the open forwardend of the receptacle; a transverse shaft arranged above and spaced fromthe endless conveyer and disposed near and withinthe forward ends ofsaid sides, a pair of radial gates carried by the shaft and arranged indiametrical relation, each gate being adapted to assume a verticalposition within the open end of the receptacle to close the same whilethe other gate is disposed wholly exteriorly of the receptacle, andgearing connecting said shaft and endless conveyer to cause them to movein unison whereby the endless conveyer is adapted to completelydischarge the material from the receptacle by the time the gate reachesthe vertical In testimony whereof, I have signed my name to thisspecification in the presence of two subscribing witnesses. I OLOF,FRANKMAN.
